RHBA-2011:0269 - Bug Fix Advisory
Synopsis
dlm-kernel bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated dlm-kernel packages that fix several bugs and module-loading issues are
now available for Red Hat Enterprise Linux 4.9, kernel release 2.6.9-100.EL.
Description
The dlm-kernel modules allow the Distributed Lock Manager (DLM) to communicate
with the kernel.
This update fixes the following bugs:
- Previously, the "ls" command could cause directories to become unresponsive
and stay in uninterruptable sleep when using the Global File System (GFS), due
to a rare race condition. With this update the "ls" command no longer causes
directories to be suspended. (BZ#495600)
- Previously, a custom dlm application could in certain cases become suspended
during node shutdown with dlm_unlock messages. With this update, this issue no
longer occurs during node shutdown. (BZ#645531)
Note: Also, these updated dlm-kernel packages are synchronized with the latest
kernel (2.6.9-100.EL). The modules in earlier dlm-kernel packages fail to load
because they do not match the running kernel. It is possible to force-load those
modules. However, with this update, force-loading the modules is no longer
required.
All users are advised to upgrade to these latest dlm-kernel packages, which are
updated for use with the 2.6.9-100.EL kernel.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
